Product Description

28.5V Dc Power Supply

This series products adopt high frequency electronic switch changing technology,design and manufacture for air and military electrical equipment of 28.5V DC switch power,it a product instead of thyristor-controlled DC Source.

Application:

It can be used in aircraft and on-board equipment, radar, navigation and other electronic equipment military,and other needs 28.5V or 24V DC power supply field.And for all panzer and tanks, planes, guns, the power to start using.

★Power devices using a new generation of IGBT,use of IGBT switching mode high-frequency low-loss characteristics,complete energy conversion, with a small size, light weight, high efficiency, high reliability

★Current-mode control with full-bridge conversion, PWM control, and slope compensation technique, without anti-bias magnetic capacitors in series, with fast dynamic response, shock load capability, the advantages of a reliable over-current protection

★Intelligent monitoring using micro-chip computer to complete the power of intelligent control, LED / LCD panel display power supply operation parameters and working conditions; with a self-diagnostic features ,can remember the recent failures, improve maintainability

★Functional units and components, all designed to be modular structure, via the components of series expansion, small size, high efficiency, reliability and good maintainability

★Machine with 19 "standard chassis structure, either alone or rack can be installed
